Chemical Structure

N-Nitroso Flecainide EP Impurity B CAS CATO-C4X-25467 chemical structure

Description

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO supplies N-Nitroso Flecainide EP Impurity B (CAS CATO-C4X-25467), a pharmacopoeial impurity reference standard (molecular formula C6H13N3O, MW 143.19 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, N-Nitroso Flecainide EP Impurity B (C6H13N3O) contains an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 143.19 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
